As with all UV2 dubbings, these have a mix of primary colors that have been enhanced with UV Fluorescence and UV Reflectance dyes. We then blend these in with other fibers to achieve the overall base color while still giving it all the multi color properties of UV2. Each dubbing will kick out a host of color spectrums. Check them out in direct sunlight.
*It is best to always use a pearl or silver Mylar under base or even basic white thread which will bounce any light back out of the pattern at a different wave length. Enjoy catching more fish than your partner.
